Min massiva ebenholtsskaft blir okontrollerbar

My massive ebony shaft is becoming uncontrollable, and I can't seem to keep it in check. It's a problem that's been plaguing me for quite some time now. My wife, bless her, has been trying her best to help me, but nothing seems to work. She's even resorted to humiliating me, which only makes the situation worse. I've been cheating on her with a stunning black beauty, and my wife knows it. She's not angry, just frustrated. She's been trying to dominate me, but it only makes my cock harder. It's a strange feeling, being dominated by a woman who used to be my everything. I don't know what to do. My wife's constant reminders of my infidelity only serve to fuel my desire for her. It's a dangerous game we're playing, but it's one I'm willing to risk for the thrill of it all.
